  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • reading video mpegts stream from stdin using libavformat libavcodec

    1er février 2012, par D Starkweather

    I'm trying to read video frames from stdin using ffmpeg's libav* lib collection. Simply passing "pipe:0" or "pipe :" as the filename to avformat_open_input_file() in my program does not do the trick. (e.g. cat /dev/video0 | ./myprogram OR ./myprogram < /dev/video0 ; it also fails using file.avi in place of /dev/video0).

    Peeking into ffmpeg.c, I find the following bit of code using tcsetattr() to set the termios :

    struct termios tty;
    

    
if (tcgetattr (0, &amp;tty) == 0) {
    
oldtty = tty;
    
restore_tty = 1;
    
atexit(term_exit);
    

    
tty.c_iflag &amp;= ~(IGNBRK|BRKINT|PARMRK|ISTRIP
    
                      |INLCR|IGNCR|ICRNL|IXON);
    
tty.c_oflag |= OPOST;
    
tty.c_lflag &amp;= ~(ECHO|ECHONL|ICANON|IEXTEN);
    
tty.c_cflag &amp;= ~(CSIZE|PARENB);
    
tty.c_cflag |= CS8;
    
tty.c_cc[VMIN] = 1;
    
tty.c_cc[VTIME] = 0;
    

    
tcsetattr (0, TCSANOW, &amp;tty);
    
}
    
signal(SIGQUIT, sigterm_handler); /* Quit (POSIX).  */
    
}
    

    
avformat_network_deinit();
    

    
signal(SIGINT , sigterm_handler); /* Interrupt (ANSI).    */
    
signal(SIGTERM, sigterm_handler); /* Termination (ANSI).  */
    
signal(SIGXCPU, sigterm_handler);

    However, when I try this, it appears to have no effect. What settings do I need in the termios struct to continuously read video frames in ?

    Currently, all i am able to do is call av_read_frames a few times (return code 0) before it usually either segfaults or hangs waiting. The buffer usually contains just a blank screen (all black). With any luck, the video buffer will contain the first video frame it comes across, but does not update to the later frames.

    (I'm running this on Debian 6.0) Here's my version of ffmpeg :

  • ffmpeg copyts to preserve timestamp

    13 avril 2015, par Bala

    I am trying to modify an HLS segment transport stream, and preserve its start time with ffmpeg. However the output does not preserve the input file’s start_time value, even if -copyts is mentioned. Here’s my command line :

    ffmpeg  -i fileSequence1.ts -i x.png -filter_complex '[0:v][1:v]overlay[out]' -map '[out]' -map 0:1 -acodec copy -vsync 0 -vcodec libx264 -streamid 0:257 -streamid 1:258 -copyts -profile:v baseline -level 3 output.ts

    The start_time value is delayed about 2 seconds consistently.

    /Users/macadmin/>ffmpeg -y -v verbose -i fileSequence0.ts -map 0:0 -vcodec libx264 -copyts -vsync 0 -async 0 output.ts

  • Progressive or Interlaced misinterpreted when transcoding to DNxHD mxf with ffmpeg

    19 avril 2015, par Olle

    Hi, don’t know if i am doing it wrong or is there a bug.

    Trying to transcode 1080i Video from Quicktime Animation interlaced upper field with a stereo audio to MXF, DNxHD with discreet mono audio channels and video interlaced.
    DNxHD = VC-3 op1a 120M.

    Everything works as a charm except for the end result is being tagged as Progressive ! I can see, when i look at the video, that it is interlaced and good looking, so everything is in order.

    But the MXF file is identifying it self as a Progressive video, so our asset management system treat it as a progressive file 1080p and so does the Avid Mediacomposers.

    I can’t se the problem with ffprobe but i can in MediaInfo v0.7.69
    Se below.

    Command that i run :

    ./ffmpeg -i OLLETEST_MANSZELM_ANIMATION.mov -timecode 10:00:00:00 -threads 16 -map 0:0 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -vcodec dnxhd -b:v 120M -acodec pcm_s24le -ar 48000 -flags +ildct -y test.mxf

    The transcoded file run with media info reports this strange result.

    Scan type                                : Progressive
    
Original scan type                       : Interlaced
    
Original scan order                      : Top Field First

    seems as -flags +ildctdon’t affect Scan type :

    The output from ffmpeg :

    Olles-MacBook-Pro-2:NoBackUp olso$ ./ffmpeg -i OLLETEST_MANSZELM_ANIMATION.mov -timecode 00:10:00:00 -threads 16 -map 0:0 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -vcodec dnxhd -b:v 120M -acodec pcm_s24le -ar 48000  -flags +ildct -y test.mxf
